Differences in surface and subsurface mining
Subsurface mining does not cause as much widespread damage to ecosystems as surface mining.
Examples of surface mining: strip mining, open pit mining, and mountain top removal.
Examples of subsurface mining: slope, drift, and shaft mining.
Surface mining effects: habitat destruction, soil erosion.
Strip mining: type of surface mining involves the removal of a thin layer of material known as overburden.
Open pit mining: surface mining technique of extracting rock/minerals from the earth.
Mountain top removal: form of surface mining that involves the mining of the summit ridge of a mountain.
Subsurface mining effects: drainage of water
Slope mining: method of accessing valuable geological material, such as coal or ore.
Drift mining: mining of an ore deposit or working of coal seams.
Shaft mining: method of excavating a vertical or or near-vertical tunnel from the top down.
